NEW YORK (Reuters Health) – Women who wake up early in the morning are unlikely to develop breast cancer like others, a new study found.
In the study, more than 400,000 women from the University of Bristol found that women who were sleeping too long (more than 8 hours) received a 20% higher risk of cancer from extra sleep.
One explanation could be good sleep and waking up early in the morning. Women who are more active in the evening than severe sleep disorder are likely to have a higher risk of cancer.
According to the Daily Mail, sleeping late at night affects the woman's body clock and increases the risk, reflecting the results of previous studies that show that night work and exposure to industrial light at night increases cancer's appearance.
The team, who presented the results at the Glasgow National Cancer Institute's national conference, analyzed and investigated female genes.
"We want to do more work to investigate mechanisms that support results," says Rebecca Richmond, MD. "Assessments are based on morning and evening sleep issues and may be more complicated than changes in women's breast cancer habits".
"Changing sleep habits is not as easy as other risk mitigations found, as they are often a key part of jobs, parents or other health conditions," says Dr. Emma Penry of the Breast Cancer Society.
The study found that women who were in early diagnosis were 48% less likely to develop breast cancer.
